P keeps appearing

When doing long calculations P keeps appearing and then I have to start over. How do I make it stop? What does it mean? I no longer have a manual for this adding machine.

Have same problem with the randomly appearing"P" and no end frustration with it. Tried loosening, (...the screws very extreemly tight), tried with no success, then tightened again, but still no success. Thanks, though, for the suggestion!

Have the same problem! Put it on our deck during the
full moon, but that didn't help any more than loosening and tightening the screws! Have to find a new one, I guess.

I've used this prodect for abuot 1 week, and today in the middle of adding numbers, it stopped working, and has an E on the left side. I can no longer type in anything.

Hi stephanie.
Try unplugging it, then plugging back in. That should reset it.
Sometimes these machines seem to think we're trying to do what they are not capable of so they go into information overload.
If you got a manual with the unit there may be a full explanation.
Usually E just means "error" and the machine cannot do what it thinks you have requested.

What does that mean adding? Displaying extra zeros? If that is the case Press [2nd][.] and limit the number of decimal you want.
You can put the calculator in FLOating mode: Press 2nd DRG and choose FLO.

How do you calculate standard deviation?

  1. Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
  2. However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
  3. Data input always starts with [SHIFT][SAC], to clear the registers of old data.
  4. Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.
After you finish entering the data

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual.

The most likely reason is that the backup battery is drained. Change the backup battery. When you get the Ram Cleared message, just press [CLEAR] to erase the message and start using the calculator.
Hope it helps.

My cash register (Sharp XE-A202) is suddenly no longer allowing me to make entries in the 'reg' mode, coming up with the error message E34. I shave consulted the manual and it says the action to take is...

Ok. This means you have accidentally programmed an amount limitation. I can help you with this. You need to tell me which button is making the error appear, then we can sort it out.

Standard deviation

image001.gif Enter the first number, 1.
image001.gif Hit the σ+ (Sigma+) key. ( n=1 will appear in the window)
image001.gif Enter the second number, 1.
image001.gif Hit the σ+ (Sigma+) key. (n=2 will appear in the window)
image001.gif . . . . .
image001.gif Enter the last number, 7.
image001.gif Hit the σ+ (Sigma+) key. (n=7 will appear in the window)
image001.gif Hit 2nd x2 (by hitting the 2nd key you are actually selecting the x-bar written above the key.) This gives you the mean.
image001.gif Hit 2nd sqrt(x). This gives you the sample standard deviation which we will use in class.
image001.gif Make sure you turn your calculator off and on for new data sets.
